Travelling Cranes

In some cases cranes are mounted on rail tracks which may be either temporary or permanent.

The tracks must be laid on a firm foundation and a secure and even running surface provided.Materials which could obstruct the crane wheels on the tracks must be prevented from finding their way on to the rails, and the rail tracks must be provided with stops or buffers at each extremity to prevent de-railment of the crane.

The requirement for electrically earthing the rail tracks, originally contained under Regulation 7, were superseded by the Electricity at Work (Jersey) Regulations, 1983. In order to meet the requirements of these regulations, the rail tracks must also be "earthed" electrically so as to ensure that if an electric fault occurs, any dangerous electrical charge which may develop can be safely discharged to earth via the rail track. In assessing whether or not rails are efficiently earthed, the possibility of deposits (which cannot be avoided) accumulating on the track, must be taken into consideration. These deposits, which may be due to infrequent use, excessive dust or otherwise, could resist the safe discharge of an electrical current.
